Be it lmown that I, Howann E. Jones, a citizen of the United States,residing at and Sta'te of Pennsylvania, have invented certain new anduseful Improvements in Milk Pasteu'rizers and Regenerators, of which thefollowing is'a specification.

iiiy invention relates to improvements'in a millr'past'eurizer andregeneratonan'd the ob jectof my invention is to'provide meansforgradually heating the milk, to a high tempera'tiue without the milkhaving a cooked I tastefth s' l accomplish by forcing the mill:

through a series of pipes towards the source of heati I i fiuther''object of my invention is to util ze the'hot milk,"as' it'leaves theapparat'us, for increasing thetemperature of the I tively.

cold 'inilk ast'he latter enters. This also tends to reduce thetemperature "of the milk afterit has been pasteurized.

in the accompanying drawings, Figure 1. is a vertical, longitudinalsectional view of my improved pasteurizer and regenerator; Fig. 2. is anend view of Fig.1. with the end plate or cap removed; Fig.3. is apartial plan view showing one or" the fasteners for securing the endplates or caps; and, Fig. 4. is a horizontal section on line la Fig. 1.

Referring to the drawings 1 and 2 represent the end heads, each having acap or plate 3 and a respectively; which said caps are ntly secured tosaid heads by clamps 5, said clamps are adapted to swing on removablepins 6, mounted in the lugs 7, so that said caps may be removed for thepurpose of cleaning the 111 i; pipes.

Between the heads 1 and 2- are a series of pipes 8 which connect withthechambers 9 and 10, formed in the heads 1 and 2 respec- The said chambers9 and 10 in the heads 1 and 2 are arranged so that the mill; as itenters the apparatus through the bot- "tom pipe 8 will be directed. intothe pipenext above, the milk passes tlnough the SBIIGS oi pipes 8 untilit passes through the pipe 12 and into the chamber 13 in the head 1.Said chamber 13 carries the milk upwards until it reaches the pipe 14.The milk passes through said pipe 14 to the chamber 15 in the head 2,which directs the milk into the next pipe 16, communicating with achamber 17, in the head 1,. and so on up through the series of pipes 16until it reaches the pipe 18 Specification of Letters Patent.

I at the top of the apparatus, as indicated by the arrows.

The pipes 14 and 1S, and theintermediate pipes 16 are each inclosed inlarger pipes 20 through which hot water is circulated inthe oppositedirection from that in which the milk ilows in the pipes 14, 16 and 18.The ends of he pipes 20 are secured in the heads 1 and 2 and communicatewith the chambers 22 and 23 formed in the h 2, respectively, so that acont-ii ious passage for the hot water is provided from the inlet pipe25 at the top, to the outlet pipe 26,'fromthe lowest pipe 20:

The mill; aiterit is heated returns from the pipe 18 through the chamber28, formed in the head 1, from which it passes into the pipe 30. Saidpipe is ided with per-- forations through which milk is discharged anddistributed over outside of the pipe 12- and the pipes 8, for the doublepurpose of cooling it and for heatin the milk which is entering theapparatus through the said pipes 8 and 12 T he water is heatedin'theiollowing manner: a'standpipe '35, as shown in Figs. 2 and i, isconnected with the, discharge outlet 26, from one of the chambers 22 inthe head 1. The said stand-pipe 35, extends above the top of thepasteurizer and is provided with an overflow pipe 36. Thus the pipes 20are always kept filled. The water is drawn from the standripe into asuction 'i 38. Steam is forced into said suction i 38 through thereduction nozzle 39, the end of which is located adjacent the end of thesleeve 40. By this means the steam forces the water through the sleeve4-0 and. the inlet pipe25, into the pipes 20, and causes the water tociroulate through said pipes 2i). The water is heated by the steam whichenters the suction l 38, and also by the steam pipe connected with. thestand-pipe, 35. The milk is pumped into the apparatus through the bottompipe 8 and travels up through the pipes 8, 12, 14, 1t and 18 and isgradually heated as it ascends to the pipe 18 at the top, where the milkreaches its highest temperature, due.

to the fact that the hot water, as it first comes from the heatercomesin contact with the top pipe 18 containing the milk. The tem erature ofthe water is, raduall reduced as it descends to the lowest one of thepipes 26. As the milk 18 forced 1n the opposite d1- rections from thehot water it Wlll inst meet the water when the latter is at its lowesttemperature so that the heatingofthe milk will be gradual. 'Bydischarging the hot milk over'the outside of the pipes 8 .and 12 throughwhich the milk is first admitted, the

temperature of the milk in the latter pipes will be raised to a hightemperature before,

from having a cooked taste after it has:

been pasteurized. The live steam never comes in contact with the milkpipes so that the milk cannot burn or scorch.

In place of having the pipes 16 and 20 in the pasteurizer arranged in avertical line, as shown, they may be placed in any other positionwithout departing from my invention as only the cooling pipes 8, 12 and30 are 'required'to be one above the other, where the milk descends bygravity and I do not wish to limit my invention to the present method ofheating and circulating the water as any other suitable form may beused.

Having thus described my invention I claim and desire to secure byLetters Patent. 1. In a device of the character described thecombination of a plurality of pipes, heads upper-milk pipe with saiddischarge pipe,

said discharge pipe adapted to distribute the milk over a number of thepipes through which the milk first'passes upon entering the.

larger pipes, a stand-pipe, means for heating,

the water and forcing it from said stand-pipe through said larger pipesand a discharge pipe for said milk adapted to distribute said milk overthe pipes which are not incas'ed in said larger pipes.

3. In a device of the character described, the combination of pipesthrough which milk is forced, means for connecting the ends of saidpipes to form a continuous passageway through the same, larger pipesincasing said first mentioned pipes, means for connecting the ends ofsaid larger pipes to form a continuous passage through said larger 1pipes,

means for forcing a. heating medium through said larger pipes, adischarge pipe, means for connecting said first mentioned pipes withsaid 'discharge'pipe, a series .of pipes into which the milk is firstadmitted, and said discharge pipe arranged? to distribute the milk oversaid last mentioned seriesof pipes.

In testimony whereof I affizrmy signature in presence of two witnesses.
